  34. help
  35. The C6X function call instruction has a limited range of +/- 2MiB.
  36. This is sufficient for most kernels, but some kernel configurations
  37. with lots of compiled-in functionality may require a larger range
  38. for function calls. Use this option to have the compiler generate
  39. function calls with 32-bit range. This will make the kernel both
  40. larger and slower.
  41. If unsure, say N.

  52. On some architectures there is currently no way for the boot loader
  53. to pass arguments to the kernel. For these architectures, you should
  54. supply some command-line options at build time by entering them
  55. here.

  61. Set this to have arguments from the default kernel command string
  62. override those passed by the boot loader.
  63. config CPU_BIG_ENDIAN
  64. bool "Build big-endian kernel"
  65. default n
  66. help
  67. Say Y if you plan on running a kernel in big-endian mode.
  68. Note that your board must be properly built and your board
  69. port must properly enable any big-endian related features
  70. of your chipset/board/processor.
  71. config FORCE_MAX_ZONEORDER
  72. int "Maximum zone order"
  73. default "13"
  74. help
  75. The kernel memory allocator divides physically contiguous memory
  76. blocks into "zones", where each zone is a power of two number of
  77. pages. This option selects the largest power of two that the kernel
  78. keeps in the memory allocator. If you need to allocate very large
  79. blocks of physically contiguous memory, then you may need to
  80. increase this value.
  81. This config option is actually maximum order plus one. For example,
  82. a value of 11 means that the largest free memory block is 2^10 pages.

  110. Usually the pointer transfer from user space is checked to see if its
  111. address is in the kernel space.
  112. Say N here to disable that check to improve the performance.
